Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A mosquito cell which undergoes mitosis has 6 chromosomes. How many chromosomes will the daughter cells have?
A
3
B
6
C
12
D
24
Explanation: 

Detailed explanation-1: -Answer and Explanation: A mosquito cell has 6 chromosomes at the start of mitosis, these chromosomes are double-stranded. At the end of mitosis, this cell will have divided into two daughter cells that also contain 6 chromosomes each. Therefore, each daughter cell will be given 6 chromosomes (single-stranded).

Detailed explanation-2: -If a cell containing 6 chromosomes undergoes mitosis cell division, the resultant two daughter cells will also contain 6 chromosomes each.

Detailed explanation-3: -In the process of mitosis, two daughter cells are produced.

Detailed explanation-4: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

Detailed explanation-5: -1) The diploid cell has 6 chromosomes. 2) During Meiosis, the two sets of chromosomes line up on the Metaphase I plate and exchange genetic material. 3) This process results in 24 new chromosomes.
